ValidatorContext

ValidatorContext holds contextual information during validation. It tracks the path of nested properties being validated and whether a value previously existed in the schema. This context is used internally by validators and by SchemaError to produce informative error messages.

Constructor

declare class ValidatorContext {
    public constructor();
    public constructor(existed: boolean);
}

Parameters

Parameter	Type	Description
existed	boolean | undefined	Whether the property existed in the object (distinguishes missing vs. undefined). Defaults to true.

Methods

declare class ValidatorContext {
    public createChild(name: string | number, existed: boolean): ValidatorContext;
}

Creates a new ValidatorContext as a child of the current context, appending the given name to the validation path.

const childContext = parentContext.createChild("fieldName", true);
